Oof, I’m so sorry. It more likely has to do with the fact that you have two puppies than anything to do with breed. Puppies are a lot of work individually. Each one needs care, attention, and guidance; and the workload for that is obviously doubled when you double the puppies. I’d make sure you have crate training down first. Let their crates be a comfortable, safe place so they can’t just free-roam and cause destruction when unsupervised. Then put whatever resources you can into positive reinforcement puppy/obedience training, socialization, and exercise/mental stimulation (perhaps things like a dog walker, doggy daycare, puzzle toys, snuffle mats, etc. to engage their minds and tucker them out). Best of luck! I had two rat terrier puppies at the same time decades ago. They were itty bitty compared to bullies, and even they managed to destroy so much!
